Description

Die Erfindung bezieht sich auf eine Steckdosenanordnung, bei der Zuleitungen zu der/den Steckdose(n) durch einen mit der/den Steckdose(n) in demselben Gehäuse untergebrachten Fehlerstromschutzschalter gesichert sind, wobei das Gehäuse zumindest an einer Seitenwand einen als Steckdosenabdeckung ausgebildeten Einsatzteil formschlüssig nach Art von Nut und Feder aufnimmt, dessen Frontfläche zur Stellfläche der Anordnung schräggestellt ist, und wobei in dem Gehäuse durch Zwischenwände Kammern gebildet sind.The invention relates to a socket arrangement in which supply lines to the socket (s) are secured by a residual current circuit breaker accommodated with the socket (s) in the same housing, the housing at least on one side wall with an insert part designed as a socket cover in a form-fitting manner takes up in the manner of tongue and groove, the front surface of which is inclined to the footprint of the arrangement, and wherein chambers are formed in the housing by partition walls.

Bei einer derartigen bekannten Anordnung (US-A-3 663 864) ist an einem Kabelende ein Gehäuse angeordnet, das an einer nach unten schräg nach vorn vorlaufenden Fläche mehrere ungeschützte Steckeraufnahmen bildet. In Kammern, die durch Zwischenwände gebildet werden, sind die Bauteile von Fehlerstromschutzschaltern untergebracht. Hierbei ist das Wiedereinschalten der Fehlerstromschutzschalter entweder mühsam oder die Bauteile der Fehlerstromschutzschalter sind nicht spritzwassergeschützt unterzubringen. Eine solche Steckdosenanordnung erfordert auch besondere Anpassungsmassnahmen, um die Bauelemente eines handelsüblichen Fehlerstromschutzschalters in der Steckdosenanordnung unterzubringen.In such a known arrangement (US-A-3 663 864), a housing is arranged at one end of the cable, which housing forms a plurality of unprotected plug receptacles on a surface which slopes forward at a downward angle. The components of residual current circuit breakers are housed in chambers formed by partitions. Here, the reactivation of the residual current circuit breaker is either tedious or the components of the residual current circuit breaker must not be protected against splash water. Such a socket arrangement also requires special adaptation measures in order to accommodate the components of a commercially available residual current circuit breaker in the socket arrangement.

Der Erfindung liegt die Aufgabe zugrunde, eine Steckdosenanordnung der eingangs geschilderten Art so weiter zu entwickeln, dass sie handlich, robust und betriebssicher ist und sich auch leicht fertigen und montieren lässt.The invention has for its object to develop a socket arrangement of the type described so that it is handy, robust and reliable and can also be easily manufactured and assembled.

Die Lösung der geschilderten Aufgabe besteht darin, dass das Gehäuse im wesentlichen die Form eines Würfels aufweist, dessen normalerweise der Stellfläche der Steckdosenanordnung zugewandte Seite als offener überstehender Rand ausgebildet ist und einen Stauraum für ein Anschlusskabel bildet, dass in dem Gehäuse von der genannten Stellfläche aus gesehen über den Stauraum eine Abdeckung liegt, die mit einem Ansatz am Einsatzteil formschlüssig nach Art von Nut und Feder ineinandergreifend derart angeordnet ist, dass Abdeckung und Einsatzteil den Steckdosensockel und Fehlerstromschutzschalter aufnehmenden, oben liegenden Geräteraum des Gehäuses vom Stauraum abtrennen, dass an die Abdekkung eine zwischen Fehlerstromschutzschalter und Steckdosensockel liegende Trennwand angeformt ist, dass der Fehlerstromschutzschalter zwecks Bedienung vom Stauraum her durch einen in der Abdeckung angeordneten Klappdeckel zugänglich ist und dass die den Fehlerstromschutzschalter zugewandten Seiten der Wände des Gehäuses, der Trennwand und/oder der Abdeckung so auf die Abmessungen des Fehlerstromschutzschalters abgestimmt sind, dass er im Passsitz federnd gehalten ist.The solution to the described problem is that the housing essentially has the shape of a cube, the side of which normally faces the mounting surface of the socket arrangement is designed as an open projecting edge and forms a storage space for a connecting cable that in the housing from the above-mentioned mounting surface seen over the storage space is a cover, which is arranged with an attachment on the insert part in a form-fitting manner in the manner of tongue and groove, such that the cover and insert part separate the socket compartment and residual current circuit breaker-receiving device compartment of the housing from the storage space, so that there is a cover on the cover is formed between the residual current circuit breaker and socket base that the residual current circuit breaker is accessible for operation from the storage space through a hinged cover arranged in the cover and that the sides of the walls facing the residual current circuit breaker of the housing, the partition and / or the cover are matched to the dimensions of the residual current circuit breaker in such a way that it is resiliently held in the snug fit.

Dadurch lässt sich der hohe Schutzpegel von empfindlichen Fehlerstromschutzschaltern, beispielsweise mit einem Nennfehlerstrom von 10 mA, nutzen. Insbesondere können hierbei handelsübliche Fehlerstromschutzschalter bei der Herstellung der Steckdosenanordnung ohne besondere Anpassungsmassnahmen eingesetzt werden. Die Steckdosenanordnung kann vor allem in Altanlagen mit vorhandener Installation sowie im Freizeitbereich zusätzliche Sicherheit bei Komfort bieten. Durch die Kubusform wird der Raum gut genutzt, so dass ein verhältnismässig kleines Gerät erzielt wird und durch die besondere Anordnung des Kabelstauraums wird die bedienungsfreundliche Handhabung und die Sicherheit für die Anschlussleitung gefördert.This enables the high protection level of sensitive residual current circuit breakers, for example with a nominal residual current of 10 mA, to be used. In particular, commercially available residual current circuit breakers can be used in the manufacture of the socket arrangement without any special adaptation measures. The socket arrangement can offer additional safety and comfort, especially in old systems with existing installation and in the leisure area. The cubic shape makes good use of the space, so that a relatively small device is achieved, and the special arrangement of the cable storage space promotes user-friendly handling and safety for the connecting cable.

Das formschlüssige Zusammenfügen von Einsatzteil und Abdeckung, die gemeinsam formschlüssig in das Gehäuse eingesetzt werden können, ergibt ein einfach zu montierendes und dichtes Gehäuse. Ausserdem liegt der Fehlerstromschutzschalter auch dann vor witterungsbedingten Störeinflüssen und solchen der Handhabung geschützt untergebracht, wenn das Gerät mit dem offenen Rand nach oben hingestellt wird.The form-fitting assembly of insert and cover, which can be inserted together in a form-fitting manner in the housing, results in an easy-to-assemble and tight housing. In addition, the residual current circuit breaker is also protected against weather-related interference and handling when the device is placed with the open edge upwards.

Dadurch, dass die Abdeckung neben dem Platz für den Fehlerstromschutzschalter eine quer zur Fläche der Abdeckung stehende Trennwand bildet, die formschlüssig in das Gehäuse eingepasst ist, und der Platz für den Fehlerstromschutzschalter als Klappdeckel ausgebildet ist, wird der Fehlerstromschutzschalter einerseits leicht zugänglich und anderseits in allen Aufstellungslagen des Gerätes vor Störeinflüssen geschützt. Dadurch wird wieder die Sicherheit des Gerätes weiter gefördert. Die aus der Geräteabdeckung des Fehlerstromschutzschalters herausschauenden Bedienungselemente werden also durch den Klappdeckel abgedeckt.The fact that the cover next to the space for the residual current circuit breaker forms a partition that is transverse to the surface of the cover, which is fitted into the housing in a form-fitting manner, and the space for the residual current circuit breaker is designed as a hinged cover, makes the residual current circuit breaker easily accessible on the one hand and on the other hand in all The installation positions of the device are protected against interference. This further promotes the safety of the device. The operating elements that look out of the device cover of the residual current circuit breaker are therefore covered by the hinged cover.

Wenn das Einsatzteil hinsichtlich seiner Frontfläche von der Gehäuseoberseite aus zurückfluchtend schräggestellt ist, wird in der Hauptarbeitslage sichergestellt, dass die Steckdosen vor Feuchtigkeit und Schmutz geschützt sind und sich zugleich eine Griffmulde ergibt.If the insert is tilted backwards from the top of the housing with regard to its front surface, it is ensured in the main working position that the sockets are protected from moisture and dirt and at the same time there is a recessed grip.

Eine Zugentlastung für eine Anschlussleitung kann in besonders einfacher Weise dadurch erzielt werden, dass im Anschlussbereich für den Fehlerstromschutzschalter in der Trennwand und in der Abdeckung Ausnehmungen ausgebildet sind, die zusammen einen Labyrinthpfad für die Anschlussleitung bilden. Dadurch kann das Kabel ohne zusätzliche Mittel bei geeigneter Bemessung der Ausnehmungen sicher festgeklemmt und die Anschlussstelle zugentlastet werden.A strain relief for a connection line can be achieved in a particularly simple manner in that recesses are formed in the connection area for the residual current circuit breaker in the partition and in the cover, which together form a labyrinth path for the connection line. As a result, the cable can be securely clamped without additional means if the recesses are suitably dimensioned and the connection point can be relieved of strain.

Für den Passsitz des Fehlerstromschutzschalters zwischen Trennwand und/oder Abdeckung mittels dünner Rippen eignen sich insbesondere Rippen aus Polypropylen. Dadurch wird ein besonders federnder Passsitz erzielt.Ribs made of polypropylene are particularly suitable for the snug fit of the residual current circuit breaker between the partition and / or cover using thin ribs. This creates a particularly springy fit.

Es ist günstig, wenn das Einsatzteil hinsichtlich seiner Frontfläche um 10 bis 30° schräggestellt ist. Besonders vorteilhaft hinsichtlich Sicherheit und einer raumsparenden Anordnung der Steckdosensockel ist es, wenn das Einsatzteil um 15° schräggestellt ist. Hierbei weist die Frontfläche des Einsatzteils zur Hauptaufstellfläche.It is advantageous if the insert is inclined by 10 to 30 ° with respect to its front surface. It is particularly advantageous with regard to safety and a space-saving arrangement of the socket bases if the insert is inclined by 15 °. The front surface of the insert faces the main installation area.

Es fördert die Bedienungsfreundlichkeit, wenn der Klappdeckel aus durchsichtigem Material ausgebildet ist. Der Schaltzustand des Fehlerstromschutzschalters kann dann bei geschlossenem Klappdeckel jederzeit erkannt werden.It promotes ease of use if the hinged lid is made of transparent material is trained. The switching status of the residual current circuit breaker can then be recognized at any time when the hinged cover is closed.

Ein montagefreundliches und leicht zu bedienendes Scharnier für den Klappdeckel erzielt man, wenn der Klappdeckel an zurückgesetzten Rändern angeformte Lagerzapfen aufweist, die zum Teil von einer Überdeckung mit Abstand überspannt sind. Die Abdeckung des Gehäuses bildet hierzu gabelförmige Aufnahmen für die Lagerzapfen, deren randseitiger Gabelarm im Ausmass der Dicke der Überdeckung am Klappdeckel verkürzt ist. Die Lagerzapfen sind dadurch toleranzausgleichend leicht federnd ausgebildet und dennoch abgedeckt. Am verkürzten Gabelarm kann in geöffneter Position der Klappdeckel bei montierter Abdeckung leicht eingesetzt werden.A hinge for the hinged cover that is easy to assemble and easy to assemble is achieved if the hinged cover has molded-on bearing journals on recessed edges, some of which are spanned by a covering at a distance. For this purpose, the cover of the housing forms fork-shaped receptacles for the bearing journals, the edge-side fork arm of which is shortened to the extent of the thickness of the overlap on the hinged cover. As a result, the bearing journals are designed to be slightly resilient to compensate for tolerances, but are still covered. The hinged cover on the shortened fork arm can be easily inserted in the open position with the cover installed.

Die Montage des Gerätes wird weiter erleichtert, wenn auf jedem Lagerzapfen eine Drehfeder mit entgegengesetzt wegstehenden Anschlagsenden aufgesetzt ist und jeweils ein Anschlagsende am Klappdeckel und ein Anschlagsende an der Abdeckung unter Vorspannung ansteht. Beim Einsetzen des Klappdeckels wird dann die richtige Federspannung von selbst eingestellt.The assembly of the device is further facilitated if a torsion spring with oppositely projecting stop ends is placed on each bearing journal and one stop end on the hinged cover and one stop end on the cover is under tension. When inserting the hinged cover, the correct spring tension is then set automatically.

Die richtige Federspannung und besonders die Lage des Klappdeckels in geschlossenem Zustand wird sichergestellt, wenn zwischen Lagerzapfen und lagerseitigem Rand des Klappdeckels eine Rippe der Abdeckung eingreift, die sich vom Ende des Lagerzapfens bis zur Auflagestelle am Klappdeckel des Anschlagsendes der Drehfeder erstreckt. Es ist dann auch sichergestellt, dass sich das Anschlagsende der Drehfeder, das sich am Klappdeckel abstützt, nicht zwischen Klappdeckel und benachbartem Rand der Abdeckung einklemmen kann. Allgemein bietet die Steckdosenanordnung eine für Laien angenehme Handhabung, da es im wesentlichen die Form eines Würfels aufweist, leicht zu bedienen und aufzustellen ist.The correct spring tension and especially the position of the hinged cover in the closed state is ensured if a rib of the cover engages between the journal and the bearing-side edge of the hinged cover, which extends from the end of the journal to the contact point on the hinged cover of the stop end of the torsion spring. It is then also ensured that the stop end of the torsion spring, which is supported on the hinged cover, cannot get caught between the hinged cover and the adjacent edge of the cover. In general, the socket arrangement offers a comfortable handling for laypersons, since it essentially has the shape of a cube, is easy to use and can be set up.

Der Stecker 9 kann mit seinen Steckkontaktstiften in kontaktlose Steckkontaktaufnahmen eingesteckt und bedienungsfreundlich gehalten werden. Im Rand 6 ist nach Fig. eine Ausnehmung 11 vorgesehen, die es ermöglicht, das Kabel 8 vom Stauraum 10 zu einer Anschlussstelle zu führen und das Gerät auf seinem Rand 6 in unveränderter Standlage zu halten. Es ist günstig, den oberen Bereich der Ausnehmung 11 so zulaufend eng auszubilden, dass das Kabel festgeklemmt wird, so dass das Kabel nicht herausfallen kann, wenn man das Gerät hinstellt. Das Kabel kann dann nicht zwischen Rand und Stellfläche gelangen.The socket arrangement according to FIG. 1 has in its housing 1 at least in one side wall an insert part 2 designed as a socket cover, the front surface of which is inclined to the side wall, so that it points towards the main footprint. The insert part 2 is positively connected to a cover 5 which closes the housing for socket outlet 3 and residual current circuit breaker 4 in a form-fit manner. Adjacent to the equipment room, the housing wall is drawn forward as edge 6 and provided with retaining lugs 7 (FIG. 2). These retaining lugs are webs with projecting tabs that hold the connecting line 8 in the cable storage space. The plug 9 can be inserted with its plug contact pins into contactless plug contact receptacles and held in a user-friendly manner. A recess 11 is provided in the edge 6 according to FIG. 1, which makes it possible to lead the cable 8 from the storage space 10 to a connection point and to hold the device on its edge 6 in an unchanged position. It is favorable to make the upper region of the recess 11 so narrow that the cable is clamped so that the cable cannot fall out when the device is put down. The cable can then not get between the edge and the shelf.

Einsatzteil 2 und Abdeckung 5 werden mittels Schrauben 12 im Gehäuse 1 befestigt (Fig. 2).Insert part 2 and cover 5 are fastened by means of screws 12 in the housing 1 (FIG. 2).

Die Abdeckung 5 bildet neben dem Platz für den Fehlerstromschutzschalter 4 eine quer zur Fläche der Abdeckung stehende Trennwand 13. Sie ist zwischen Wülsten 14 formschlüssig in das Gehäuse 1 eingepasst. Der Raum für den Fehlerstromschutzschalter 4 liegt über einem Klappdeckel 15. Gehäuse 1 und Trennwand 13 sowie auch die Abdeckung 5 sind mittels dünner Rippen 16 so auf die Abmessungen des Fehlerstromschutzschalters 4 abgestimmt, dass er im Passsitz federnd gehalten ist. Als Werkstoff eignet sich insbesondere Polypropylen. Hierdurch werden Stösse wirkungsvoll gedämpft.In addition to the space for the earth leakage circuit breaker 4, the cover 5 forms a partition 13 which is transverse to the surface of the cover. It is fitted into the housing 1 in a form-fitting manner between beads 14. The space for the residual current circuit breaker 4 lies above a hinged cover 15. Housing 1 and partition 13 and also the cover 5 are matched to the dimensions of the residual current circuit breaker 4 by means of thin ribs 16 in such a way that it is resiliently held in the snug fit. Polypropylene is particularly suitable as the material. This effectively dampens shocks.

Wie aus Fig. 1 zu ersehen ist, ist das Einsatzteil 2 mit der Abdeckung 5 dadurch formschlüssig verbunden, dass sie nach Art von Nut 17 und Feder 18 ineinandergreifen.As can be seen from Fig. 1, the insert 2 is positively connected to the cover 5 in that they engage in the manner of groove 17 and tongue 18.

Es ist günstig, das Einsatzteil 2 hinsichtlich seiner Frontfläche um 10 bis 30° schräg zu stellen, Wie es aus Fig. 1 zu ersehen ist. Besonders vorteilhaft ist es, das Einsatzteil um 15° schräg zu stellen. Dadurch sind die Steckdosen 3 in der Hauptgebrauchslage gegen Witterungseinflüsse geschützt und die Steckdosensockel 3 können raumgünstig untergebracht werden.It is favorable to incline the insert 2 with respect to its front surface by 10 to 30 °, as can be seen from FIG. 1. It is particularly advantageous to incline the insert part by 15 °. As a result, the sockets 3 are in the main use position against weather influences protected and the socket base 3 can be accommodated in a space-saving manner.

Wenn der Klappdeckel 15 aus durchsichtigem Material ausgebildet ist, lässt sich der Betriebszustand des Fehlerstromschutzschalters 4 jederzeit kontrollieren, ohne dass der Klappdeckel 15 geöffnet zu werden braucht. Um das Scharnier 20 im geöffneten Zustand zu entlasten, ist-es vorteilhaft, die Abmessungen so zu wählen, dass sich der Klappdeckel 15 am stirnseitigen Gehäuserand 6 abstützen kann.If the hinged cover 15 is made of transparent material, the operating state of the residual current circuit breaker 4 can be checked at any time without having to open the hinged cover 15. In order to relieve the hinge 20 in the open state, it is advantageous to choose the dimensions such that the hinged cover 15 can be supported on the front housing edge 6.

Wie aus den Fig. 1 und 2 zu ersehen ist, ergibt sich ein gedrungener und gebrauchsgQnstiger Aufbau dadurch, dass das Gehäuse im wesentlichen die Form eines Würfels aufweist. Die eine Seite des Würfels ist als offener überstehender Rand 6 ausgebildet. Auch die anderen Seiten dieses Würfels eignen sich als Auflägeflächen. Trotzdem bleibt insbesondere der Fehlerstromschutzschalter 4 vor Störeinflüssen geschützt.As can be seen from FIGS. 1 and 2, a compact and usable structure results from the fact that the housing has essentially the shape of a cube. One side of the cube is designed as an open, projecting edge 6. The other sides of this cube are also suitable as support surfaces. Nevertheless, the residual current circuit breaker 4 in particular remains protected from interference.

Im Anschlussbereich für den Fehlerstromschutzschalter 4 sind in der Trennwand 13 und in der Abdeckung 5 Ausnehmungen bzw. Durchführungen 22 ausgebildet, die zusammen einen Labyrinthpfad für die Anschlussleitung 8 bilden. Bei entsprechend enger Bemessung ergibt sich hierdurch eine sichere Zugentlastung für die Anschlussstellen des Kabels 8.In the connection area for the residual current circuit breaker 4, recesses or bushings 22 are formed in the partition 13 and in the cover 5, which together form a labyrinth path for the connection line 8. With appropriately narrow dimensions, this results in a safe strain relief for the connection points of the cable 8.

Nach Fig. 3 sind die federnden Rippen 16 in der Trennwand 13 als durchgedrückte Stege ausgebildet, wobei die ganze Trennwand mitfedert. Das Handbetätigungsorgan des Fehlerstromschutzschalters 4 ist mit 23 und die Prüftaste mit 24 bezeichnet.According to Fig. 3, the resilient ribs 16 are formed in the partition 13 as a pressed webs, the entire partition springs. The manual actuator of the residual current circuit breaker 4 is designated 23 and the test button 24.

In Fig. 4 ist die raumgünstige Anordnung von zwei Steckdosensockeln 3 veranschaulicht.The space-saving arrangement of two socket bases 3 is illustrated in FIG. 4.

Der Klappdeckel 15 nach Fig. 5 weist an zurückgesetzten Rändern 25-man vergleiche insbesondere Fig. 7 - angeformte Lagerzapfen 26 auf, die zum Teil von einer Überdeckung 27 mit Abstand überspannt sind. Die Abdeckung 5 des Gehäuses 1, nach Fig. 1, weist gabelförmige Aufnahmen 30 für die Lagerzapfen 26 auf, deren randseitiger Gabelarm 29 im Ausmass der Decke 31 der Überdeckung 27 verkürzt ist. Man vergleiche Fig. 6. Dadurch kann entsprechend Fig. 10 der Klappdekkel 15 unter einer Schwenkbewegung bis zur vollen Öffnung zum Montieren eingesetzt werden.The hinged cover 15 according to FIG. 5 has molded-on bearing journals 26 on recessed edges 25 - compare in particular FIG. 7 - which are partially spanned by a covering 27 at a distance. The cover 5 of the housing 1, according to FIG. 1, has fork-shaped receptacles 30 for the bearing journals 26, the edge-side fork arm 29 of which is shortened to the extent of the cover 31 of the cover 27. Compare FIG. 6. As a result, according to FIG. 10, the hinged cover 15 can be used for mounting with a pivoting movement up to the full opening.

Auf jedem Lagerzapfen 26 ist nach Fig. 8 eine Drehfeder 32 mit entgegengesetzt wegstehenden Anschlagsenden 33 und 34 aufgesetzt, wobei ein Anschlagsende 33 am Klappdeckel 15 und ein Anschlagsende 34 an der Abdeckung 5 an der Stufe 35 bzw. 36 ansteht. Wenn man den Klappdeckel 15 einsetzt, spannt sich dadurch die Drehfeder 32 von selbst.8, a torsion spring 32 with oppositely projecting stop ends 33 and 34 is placed on each bearing pin 26, with a stop end 33 on the hinged cover 15 and a stop end 34 on the cover 5 at steps 35 and 36 respectively. If you use the hinged lid 15, the torsion spring 32 tensions itself.

Zwischen Lagerzapfen 26 und lagerseitigem Rand des Klappdeckels 15 greift nach Fig. 9 eine Rippe 37 der Abdeckung 5 ein. Sie erstreckt sich vom Ende des Lagerzapfens 26 bis zur Auflagestelle 35 am Klappdeckel 15 des Anschlagsendes 33 der Drehfeder 32. Diese Rippe 37 hält die Lagedes Klappdeckels 15 in der Gabel 30 - man vergleiche Fig. 10 und Fig. 1 - fest. Sie verhindert ausserdem bei Erstreckung bis oberhalb der Mittellinie des Zapfens 26, dass sich das Anschlagsende 33 der Drehfeder 32 zwischen Klappdecke! 15 und Abdeckung 5 festklemmen könnte - man vergleiche Fig. 9.According to FIG. 9, a rib 37 of the cover 5 engages between the journal 26 and the bearing-side edge of the hinged cover 15. It extends from the end of the journal 26 to the support point 35 on the hinged cover 15 of the stop end 33 of the torsion spring 32. This rib 37 holds the position of the hinged cover 15 in the fork 30 - see FIGS. 10 and 1. It also prevents the stop end 33 of the torsion spring 32 between the folding ceiling when it extends to above the center line of the pin 26! 15 and cover 5 could jam - see FIG. 9.

Die Steckdosenanordnung lässt sich leicht montieren, indem Einsatzteil 2 mit angebrachtem Steckdosensockel und Abdeckung 5 formschlüssig zusammengesetzt werden und bei eingelegtem Fehlerstromschutzschalter 4 nach Verdrahtung in das Gehäuse 1 eingeschoben werden. Anschliessend wird diese Baugruppe durch Schrauben 12 festgehalten. Zuvor ist noch der Klappdekkel 15 bei aufgesetzten Drehfedern 32 in die gabelförmige Aufnahme 30 einzusetzen.The socket arrangement can be easily assembled by inserting insert 2 with attached socket base and cover 5 in a form-fitting manner and pushing it into housing 1 after an earth leakage circuit breaker 4 has been inserted. This assembly is then held in place by screws 12. Before this, the hinged lid 15 must be inserted into the fork-shaped receptacle 30 when the torsion springs 32 are attached.

Zum Montieren ist der Klappdeckel 15 dabei so weit zu öffnen, im Ausführungsbeispiel ca. 75°, dass der Absatz 40 des Klappdeckels 15 über die Rippe 37 hinwegkommt. Man vergleiche den Abstand 42 nach Fig. 10. Die Lagerzapfen 26 des Klappdeckels 15 werden also in die gabelförmige Aufnahme 30 dann eingeschoben, wobei sich die Anschlagsenden 33 und 34 der Drehfeder 32 gegen die Stufen 35 des Klappdeckels 15 und 36 der Abdeckung 5 anlegen und gespannt werden. Nachdem der Deckel geschlossen ist, verhindert die Rippe 37 zusammen mit den Stufen 35 und 36, dass sich die Drehfeder 32 wieder entspannen könnte. Der Klappdeckel 15 kann also schon bei der Vormontage nicht mehr aus der Abdeckung 5 herausrutschen.For assembly, the hinged cover 15 is to be opened so far, in the exemplary embodiment approximately 75 °, that the shoulder 40 of the hinged cover 15 comes over the rib 37. Compare the distance 42 according to FIG. 10. The journals 26 of the hinged cover 15 are then inserted into the fork-shaped receptacle 30, the stop ends 33 and 34 of the torsion spring 32 bearing against the steps 35 of the hinged cover 15 and 36 of the cover 5 and be excited. After the lid is closed, the rib 37 together with the steps 35 and 36 prevents the torsion spring 32 from relaxing again. The hinged lid 15 can therefore no longer slip out of the cover 5 during the pre-assembly.
